Agent
Goal-completion QA + fraud gate. Independently re-verifies delivered behavior against the goal's successCriteria, hunts edge cases and regressions, and hunts fake implementations (stubs, hardcoding, assertion theater); returns PASS or FAIL via a fixed C1–C12 checklist.
Agent
Binary contract critic (panel seat 2 of 3) — integration lens. Attacks a drafted ClarificationGoalContract's subgoal composition, dependency edges, interface consistency, and shared-state hazards; returns APPROVE or REJECT via a fixed C1–C6 checklist.
Agent
Binary contract critic (panel seat 3 of 3) — coverage lens. Verifies a drafted ClarificationGoalContract fully covers the user's request, contains no placeholders, and states only binary-decidable success criteria with adequate evidence; returns APPROVE or REJECT via a fixed C1–C6 checklist.
Agent
Creates implementation plans from context and requirements.
Agent
Code review specialist for quality and security analysis.
Agent
Fast codebase recon that returns compressed context for handoff to other agents.
Agent

Agent
General-purpose agent with full capabilities in an isolated context.
Agent

Agent Claude Code
Research the docs/ folder and related code in isolated context. Use for doc audits, sync scans, coverage checks, and deep reference lookups without polluting the main session's context window.
Poorgramer-Zack/copilot-cli-things
Agent
Conversation analysis for hookify — scan user messages for frustration signals, corrections, repeated issues, explicit "don't do X" requests. Detects unwanted tool behaviors and extracts regex patterns for hook rule generation. Triggered by hookify-create without arguments or explicit conversation analysis requests.
Poorgramer-Zack/copilot-cli-things
Agent
Agent creation: generate .agent.md files with optimized descriptions, system prompts, model/tool selection. Triggered by create agent, new agent, build agent, generate agent.
Poorgramer-Zack/copilot-cli-things
Agent
Plugin validation: check plugin structure, directory layout, component correctness (agents, skills, hooks, MCP). Triggered by validate plugin, check plugin, verify plugin, plugin structure.
hajekim/agentic-design-patterns-extension
Agent
Agentic design pattern architect. Recommends the optimal combination of patterns from the 28-pattern library for a given problem. Use when: designing a new AI agent system, choosing patterns, comparing pattern trade-offs, planning multi-pattern architectures.
hajekim/agentic-design-patterns-extension
Agent
Agentic design pattern compliance reviewer. Reviews code to verify it correctly implements agentic design patterns from the 28-pattern library. Use when: reviewing agent code, checking pattern compliance, validating SDK usage, catching deprecated library usage.
